Distributed Computing PRINCIPLES and APPLICATIONS pdf epub mobi txt 电子书 下载 2026

Distributed Computing provides an introduction to the core concepts and principles of distributed programming techniques. It takes a “how-to” approach where students learn by doing. The book covers computing paradigms, protocols, and application program interfaces (API's), including RMI, COBRA, IDL, WWW, and SOAP. Each chapter introduces a paradigm and/or protocol, and then presents the use of a DPI that illustrates the concept. The presentation uses narrative, code examples, and diagrams designed to explain the topics in a manner that is clear and concise. End of chapter exercises provide analytical as well as hands-on exercises to prompt the reader to practice the concepts and the use of the API covered in the chapter. Using this text, students will gain an understanding of, and be able to execute, basic distributed programming techniques used to create network services and network applications, including Internet applications.
